    摘要: A cushioned bumper for ground scrapers comprising a housing adapted to be mounted on the rear end of the scraper in a generally horizontal postion and extending longitudinally of the scraper, with the housing carrying a pair of internal stop elements, a tubular plunger structure reciprocably mounted in the housing and carrying stop lugs, adapted to engage the respective housing stop elements, and a buffer plate exposed exteriorly of the housing against which the blade of a bulldozer or the like will engage to push the scraper when struck, and a composite cushioning arrangement interposed between the housing and the plunger including spring means to bias the plunger structure outwardly against the housing stop elements, in which the sides of the housing are equipped with special stiffener elements that hold the housing stop elements and the housing side walls bearing same against displacement laterally outwardly of the housing due to recoil and the lateral forces due to the bulldozer working against the plunger in rough terrain.

    摘要: A DRAFT GEAR HAVING OPPOSED FOLLOWERS BEING UNITARILY FORMED WITH CENTRAL WEDGING SECTIONS, EACH HAVING AT LEAST TWO INCLINED FLAT SURFACES DISPOSED IN DIVERGING RELATIONSHIP WITH RESPECT TO ONE ANOTHER. A PAIR OF ALIGNMENT RIDGES OR TRACK FORMERS ARE PROVIDED ON EACH OF HE INCLINED SURFACES SO AS TO PROVIDE A SPECIFIC FRICTION PATHWAY FOR THE MOVEMENT OF FRICTION SHOES OR WEDGE ELEMENTS THEREON. THE WEDGING SECTIONS HAVE DROPOFFS OR ARE RELIEVED AT THE ENDS THEREOF SO THAT ABUTMENT SHOULDERS WILL NOT BE FORMED DURING WEAR OF THE INCLINED SURFACES BY THE FRICTION SHOES OR ELEMENTS. THE MATERIALS USED IN CONSTRUCTING THE GEAR ARE OF HIGH QUALITY STEEL AND THE WEDGING ELEMENTS OR SHOES IN CONJUNCTION WITH THE REMAINDER OF THE COMPONENTS, HAVING WORKING OR CONTACTING ENGAGEMENTS, ARE CONTOURED SO AS TO ALLOW FOR EASY

    PASSING OF THE MOVING MEMBERS, THEREBY REDUCING UNDESIRED FRICTIONAL ENGAGING CONTACTS.
